Negative number fetch in pl/sql

Hi

I would like to know why i can not fetch a negative number in a pl/sql variable when that variable use the same format as in the database, i.e. i have the following variable :

   piezo_suivant NUMBER(6,3);

which has the same format as in the database and the database contains the value -130.159 but at the :

   FETCH niveau_piezo_suivant INTO piezo_suivant;

i get the following message "trigger raised unhandled exception VALUE_ERROR"

thank in advance for any answer
